vRAIATOH, FILLING AND COOLING CAP.

Application led June 5, 1922. Serial No, 565,825.

`a citizen ot the United States, and resident loi' Kansas City, county of Vyandotte, and

State of Kansas. have invented a certain new `and useful Improvement in Radiator Filling and Cooling Gaps, of `which the following is a complete specification.

j This invention relates to combined radiator filling and cooling caps for use with automobile radiators and has for one of its obiects to produce a device which is readily adjustable for vthe` filling of the radiator, without the necessity of removing the radiatorcap. i j l Another Objectis to'produce a device of the character set forth which will maintain a current of air within the radiator for condensing any steam which may be formed and thereby maintain the water` supply substantially constant.

A further object is to produce a device of the` character described,\wliich is ornamental in appearance and is of simple, strong, durable, efficient and inexpensive construction; and in order that it may be fully understood, `reference is to be had to the accompanying drawing, inwhich Figure 1 is a front view `of the device attached to a radiator filling neck.

`Figure 2 is a central vertical section through the same, and illustrates in dotted lines the position the device will occupy when used in filling the radiator.

Figure 3 is a section on the line IIL-III` of Figure 2.

`Figure 4 is a section on the line IV--IV of Figure 2.

Figure 5 is a central vertical section through a modified form of one part of the invention.

1n the said drawing, where like reference characters identify corresponding parts in all of the figures, 1 illustrates an automobile radiator, 2 the filling neck thereof,

gaged with said threads is a tubular eXtension tformed with an abutment portion 5 adapted to come into contact with the upper extremity of the filling neck. The device projects somewhat upward above the end of the filling neck and is formed with a second abutment portion 6 and terminates `in an externally threaded reduced portion 7 kSecured within the extension 4r and preferablyla slight distance above. the horizontal plane of the top of the filling neclr' a cone deflector 8 located with its point in the vertical axis of the filling opening, and around `the base of said cone, a series of openings 9 are` formed, for' a purpose which will hereinafter appear. y y

VAdapted to be secured to the upper end of the extension 4 is the lower end ot `a funnel member .10` equipped with a mar- `efinal flange 11, at its lower end 'for resting on theextremityof the part 'Land said funnel is secured in position by means ot a threaded collar 12 in engagement with the external threads of y.the `member 7 and formedwith a lip 13 adapted to clamp down upongthe` lip 11 of the member 1() and retain samefrmly on its seat, as will be` read ily understood.

` `The funnel member 10 is curved at its upper end and is formed with a marginal flange 14.-, to which is vfreely secured for rotation, the mouth of the funnel 15, formed at its lower end with a bead 16 receiving the flange 14 ofthe lower funnel member 10. In this connection it is desirable to point out that the connection between members 10 and 15 possesses sufficient frictional resistance as to prevent accidental turning movement of the member 15. It will be evivdent from the construction just described.

that the mouthmember 15 may be rotated to occupy the dotted line position (Figure 2), when it is desired to fill the radiator.

Preferably formed integrally with the passageway of the funnel member 10 is an inverted truncated cone deflector 17, it being evident that a pocket 17a will be formed below said truncatedcone and above the cone deflector 8. j i

The construction shown in Figure 5 illustrates a slightly modified form, in which the extension 4 is formed integrally with `the inverted truncated cone 17 in addition the current of air set up by the vehicle in its course of travel. The air will enter the funnel and pass down through the truncated cone and will strike and be divided by the dei'lector 8 and will pass down through the openings 9 into the top oit the radiator, and will exit through the overow pipe 3.

lit the water in the radiator becomes excessively hot, and steam is generated, the steam will, of course, attempt to pass upwardly through the openings 9 and through the opening in the member 17, but the cool current of air passing` downward through the tunnel will chill the parts and cause a condensation oi steam aiter which the water will drain back into the radiator through the openings 9.

In order to add to the attractive and ornamental appearance of the device, a ring 175i equipped with a pair of side wings 19, er the like, is slipped on the extension 4 and rests on the abutment 5 (see Figure 2), the threaded portion of the collar 12 being received inside the upper edge of the ring. The ring 1S lis turned to the desired position and then fastened securely in such position by means of a set screw 20, as will be readily understood.

lvlhen it is desired to lill the radiator, the mouth ot' the funnel is rotated to occupy the position shown in dotted lines (Figure 2), and after the filling operation, it is again rotated to face in a forward direction to receive the current of air set up by the passage of the car, as above pointed out, it being evident that the frictional connection between the funnel members, abovementioned, will hold the mouth member of the funnel turned in any desired position of a dj ustment.

From the above description, it will be apparent that I have produced a device of the character described, which possesses all of the features of advantage pointed out as desirable, and while I have described and claimed, the preferred embodiment of the same, l reserve the right to make all changes properly falling within the spirit and scope of the appended claim.

I claim The combination with an automobile radiator nipple, of an extension threaded thereon and of reduced diameter and threaded at its upper end, a downwardly opening funnel in the upper end of said eX- tensi'on, 'a conical delector in the lower end of said yextension and alined 'with the lull opening and Jformed with a series of perfor-ations surrounding its base, a filling member resting on the upper end of the eX- tensio'n, and a collar securing said filling m'ember in position 'and having threaded engagement with the upper end of said 'extension.

In witness i'vh'ere'of I hereunto aIiX my signature.
